Origin of Mentoring1 The Greek poet Homer describes Odysseus, king of Ithaca, as having a loyal friend and advisor by the name of Mentor. While Odysseus was away fighting in the Trojan War, Mentor became a trusted teacher, coach, counselor, and protector of Odysseus’ son Telemachus. Thus, the word “mentor” used today derives from Homer and reflects a process where the mentor guides and protects...

The molecular mechanisms occurring in the nervous system that underlie behavioral responses to ethanol remain poorly understood. Here, we report that molecular requirements for two of these responses, initial sensitivity and the development of rapid tolerance, comap to the same small set of neurons. We show that null homer mutant flies exhibit both increased sensitivity to the sedative effects ...

The postsynaptic density (PSD) is crucial for synaptic functions, but the molecular architecture retaining its structure and components remains elusive. Homer and Shank are among the most abundant scaffolding proteins in the PSD, working synergistically for maturation of dendritic spines. Here, we demonstrate that Homer and Shank, together, form a mesh-like matrix structure. Crystallographic an...

The Homer help desk support system, developed in the course of the Inreca-II project, is an example of applying Case-Based Reasoning to problems of a software-intensive organization. This paper discusses, in retrospect, Homer with respect to change management processes at DaimlerChrysler and various feedback and learning possibilites that the help desk support system provided for itself, the he...

One of the most frustrating aspects of Homeric studies is that so little literary material outside the Homeric corpus itself survives to enhance our understanding of the cultural landscape of the period. Recent scholarship suggests that a large and diverse poetic tradition lay behind the figure we refer to as "Homer," but little of it survives. Indeed we have little continuous written Greek for...

Introduction:The purpose of this study was to define the etiologies of Horner syndrome in the pediatric population. Methods: A retrospective review was performed of the medical records of all pediatric Horner syndrome patients (<18 years old) examined by the pediatric ophthalmology services at two large referral centers. Results: Seventythree pediatric Horner syndrome patients were identified. ...

Activation of group I metabotropic glutamate (mGlu) receptors recruits the endocannabinoid system to produce both short- and long-term changes in synaptic strength in many regions of the brain. Although there is evidence that the endocannabinoid 2-arachidonoylglycerol (2-AG) mediates this process, the molecular mechanism underlying 2-AG mobilization remains unclear. In the present study, we use...

HOMER, the Human Oriented MEssenger Robot, is a stereovision guided mobile robot for performing human-interactive tasks. Our design concept for HOMER combines mobile robotic techniques for navigation, localization, map building and obstacle avoidance with human interaction capacities for person recognition, speech, facial expression and gesture recognition, and human dynamics modeling. HOMER’s ...
